Stock tweeters aren't working, can someone help me?

My stock tweeters were working before i installed my head unit with the wire harness that was suggested for my car, and now they don't work. I'm starting to think that it could be a wire i didn't hookup to the head unit from the wiring harness. If so, what color would the wire be and what color wire would it hook up to on my Pioneer head unit. I have the DEH-6000UB. Thanks for your help, i'm looking forward to responses so i can fix this issue.
